Accumulation functions

Functions
void	arm_accumulate_f16 (const float16_t *pSrc, uint32_t blockSize, float16_t *pResult)
	accumulate value of a floating-point vector.
void	arm_accumulate_f32 (const float32_t *pSrc, uint32_t blockSize, float32_t *pResult)
	Accumulation value of a floating-point vector.
void	arm_accumulate_f64 (const float64_t *pSrc, uint32_t blockSize, float64_t *pResult)
	Accumulation value of a floating-point vector.

Description

Calculates the accumulation of the input vector. Sum is defined as the addition of the elements in the vector. The underlying algorithm is used:

Result = (pSrc[0] + pSrc[1] + pSrc[2] + ... + pSrc[blockSize-1]);

There are separate functions for floating-point, Q31, Q15, and Q7 data types.
